Zugmayer, 1911 is an abyssal fish species inhabiting depths exceeding 3,000 m. We successfully sequenced and characterized the complete mitochondrial genome of , which represents a closed circular molecule of 16,646 bp with a GC content of 48.98%. Phylogenetic analysis of Ophidiiformes based on whole mitochondrial genome sequences demonstrated that forms a sister group with while supporting the polyphyly of Bythitidae as well as the paraphyletic status of Ophidioidei. As the first report of a complete mitochondrial genome for , this study provides valuable genomic resources for investigating deep-sea adaptation mechanisms in Ophidiiformes and contributes to our understanding of evolutionary patterns in abyssal teleost fishes.
祖格迈尔氏鱼（Zugmayer, 1911）是一种栖息于深度超过3000米的深海鱼类。我们成功地对其线粒体基因组进行了测序和特征分析，该基因组呈现为一个16,646 bp的闭合环状分子，GC含量为48.98%。基于全线粒体基因组序列对鼬鳚目进行的系统发育分析表明，[该物种名称缺失]与[另一物种名称缺失]形成姐妹群，同时支持深海鼬鳚科的多系性以及鼬鳚亚目的并系地位。作为对[该物种名称缺失]完整线粒体基因组的首次报道，本研究为研究鼬鳚目深海适应机制提供了宝贵的基因组资源，并有助于我们理解深海硬骨鱼类的进化模式。
